REFRlGERATING-CAR.

SPECIFICATION forming part of Letters Patent No. 289,977, dated December11, 188?,

Application filed September 29,1883.

ing and condensing surface which shall be free from clogging by frost,and to effect'the required reduction of temperature and condensation ofmoisture in the cheapest and most practical manner.

To this end, therefore, my invention consists in a series ofice-receptacles, each composed of wire-net or similar. open-work, andinclosed within a metallic jacket, an air-dividing partition erected infront, and a drippan beneath, with an air-space in front, be-

neath, and behind, whereby the air passes from above down and around theinclosingjacket, behind the same, and between its bottom and thedrip-pan, escaping finally below the air-partition, whereby it isexposed to a large cooling and condensing surface,while at the same timethe accumulation of frost is pre-, vented.

Referring to the drawings, Figure 1 is a transverse vertical section ofthe car or compartment, taken near one end of the same. Fig. 2 is ahorizontal section taken through the end portion of the car a littlebelow the roof.. Fig. 3 is a vertical longitudinal section of the partsshown in Figs. 1 and 2.

In said drawings, the letter A designates the end wall of the car, and Athe side walls, the construction being the same as that already knownand used.

Across the end of the car I place a metallic jacket, B, having its opentop arranged a short distance beneath the roof, while its bottom is notfar from half-way between the roof and the floor; This jacket issupported by any suitable means, and is braced or supported at intervalsby joists O, a space being left be tween the rear side of the jacket andthe end wall of the car, and between its ends and the (No model.)

side walls of the car or compartment. VVithin this jacket B,Iplacecylindrical receptacles B, formed of wire-net or an equivalent material,and having such dimensions that they project above the top of the jacketinto the opening in the roof, which is closed by a cover, D. Thediameter of these receptacles is such that they lie in contact with thesides and ends ofthe surrounding rectangular jacket,sufficient insertionof a vertical joist, a, about four inches square, .which joists sustainthe adjacent walls of the receptacles in proper upright position,

the walls. Upon the outside of the jacket-are placed joists a, bearingagainst the ends, and joists 0 along its front, and opposite the joistsO.

viding partition, E, having its top in about the same plane as the topof the jacket, and extending from side to side of the car. Afew inchesbelow the bottom of the said jacket this partition is carried toward theend wall, A,

clination being given to this portion, and it is then dropped verticallyuntil its lower edge is a little above the floor. The inner face of thepartition opposite the front side of the jacket is covered with sheetmetal F, such as copper or galvanized iron, which is extended over thatportion which lies beneath the j acket, and its edge is turned up, asshown at f, forming a drip-pan,which receives the water of condensation.An escape-pipe, G, allows the water to flow off into any suitablereceptacle, H, without the car.

The refrigerating material is placed within the wire-receptacles B,which are filled through the roof. The warm air, which rises to theupper part of the car, passes over the top of the partition E, and itstemperature is almost at once so far reduced as to change its specificgravity and give it a downward tendency. It flows down between thejacket B and the partition E, as well as between its ends and the sidewalls of the car, while at the same time a portion passes over thejacket, through the ice-receptacle B, and down between the end wall, A,and the rear side of the jacket. The air passing between the latter andthe airspace between those adjacent being left for the and resistlateral pressure on such portions of In front of the jacket B is placedan air-di- 7 beneath the bottom of the jacket, a slight individingpartition flows over the drip-pan and below the bottom of the j aeket,and the several currents finally unite behind the lower end of thepartition, and thence pass into the refrigcrating-compartment beneaththe latter. A circulation of air is thus set up, and as itstemperatureis reduced by passing through the cooling-chamber withinwhich the jacket B is placed, the moisture taken up by the warmer stratais pressed out and deposited upon the metallic surfaces of the jacketand the inner lining of the partition, as well as upon theice-receptacle and the ice or freezing-mixture itself. This, as willreadily be seen, will make a rapid active cooler.

It will be seen that by the peculiar arrangement shown and described Iobtain a comparatively large cooling and condensing surface and avoidthe clogging of the parts by the accumulation of frost upon the outsideof the vessel containing the refrigerating material.

Instead of wire-netting, other and equiva lent material may be used informing the icereeeptacles Bsueh as perforated metal plate, for example.I prefer, however, to employ Wire, as being cheaper, while it isequallystrong and well adapted to the purpose.

I am aware that foraminous ice tanks are not new, and that such tankshave been arranged in a chamber having top and bottom. openings for theentrance and exit of air at such points; but such do not constitute myinvention.

Having thus described my invention, what I claim is- 1. In arefrigerator-car, the combination of the metallic jacket B, extendingtransversely to the car-body and terminating at a distance from the roofthereof, a series of foraminous ice-receptacles, B, arranged withinsuchj acket, and having their upper ends projecting above the upper edgethereof to an opening in the car-roof,having a movable cover, D, saidreceptacles having their side walls supported by the side walls of the jacket, and the saidjacket being located to create an air-space betweenone of its transverse sides and the end of the ear, substantially asdescribed.

2. The combination, with a refrigerator-ear, of a metallic jacket, B,arranged transverse to the car-body, with air-spaces between the ends ofthe jacket and the sides of the car and between the end of the latterand one'side of the jacket, with joists sustaining the jacket in suchposition, and foraininous ice-receptacles arranged in the jacket, with aspace between, provided with joists to sustain the receptacles, saidreceptacles projecting above the upper edge of the jacket to an openingin the carroof having a movable cover, substantially as described.

3. The combination,with a refrigerator-car, of a metallic jacketextending transverse to the car-body, and arranged to create verticalair-spaces at its ends and sides, a series of foraminous ice receptaclessuspended in the jacket and projecting above the upper edges thereof toan opening in the roof having a movable cover, and means whereby thewalls of the foraminous ice-receptacles are sustained against lateralpressure at different sides,substantially as described.

4:. The co1nbination,with a refrigerator-car, of a partition extendingfrom side to side of the ear, and having a metallic inncrsurfacc. a jacket arranged transverse to the car-body, between its end wall and saidpartition, to create the i ntervening air-spaces, and a series offoraminous ice-receptacles suspended in the metallic jacket andprojecting above the upper edges thereof to an opening in the car-roof,said receptacl es having their walls braced by the walls of the jacketagainst lateral pressure, substantially as described.

5. The combinatiomwith a refrigerator-car, of a metallic jacketextending transverse to the ear-body, adjacent to the end wall thereof,and a series of foraminous ice-receptacles suspended in the jacket, anda partition extending from side to side of the car at a distance fromthe jacket, and having a metallic condensingsurt'ace presented to thejacket, substantially as described.

6. The combination,with a refrigerator-car, of a metallic jacketarranged therein to create surrounding air-spaces, and a series offoram- 9 inous ice-receptacles arranged in the jacket and projectingabove its upper edge, substantially as described.

7. The combination,with a refrigerator-car, of suspended foraminousice-receptacles, a jacket surrounding all the receptacles andterminating below their upper ends, and an air dividing and directingpartition arranged in front of the metallic jacket and extending beneaththe bottom of the said jacket, substantially as described.

S. In a refrigerating-car, the combination. with a metallic jacketarranged across the end of the car, of foraminous receptacles inclosedtherein and projecting above the same, an airdividing partition erectedin front of said jacket and extending underneath it to a point a littleabove the floor, and ametal lining covering the face of the partitionopposite the jacket and extending beneath it, and having its edge turnedup to retain the drip, and a suitable escape pipe, substantially as described.

9. The combination,with the jacket B, containing a series ofcylindricalreceptacles, 13, formed of wire-net, of the air-dividingpartition E, extending from side to side in front of the jacket,with anair-opening between it and the roof, the metal lining F, having an edgeor flange, f, and the drip-pipe G, the partition extending in frontofand beneath thejaeket and to a point a little above the floor,substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
